Abstract
The purpose of the current case study was to describe the detailed activity that occurs during the fight time and comparison of each exponent of a silat olahraga about. Video recording of 4 matches’ international silat olahraga bout was and notated for used to identify 14 different types of event performed by the 6 contestants as well as the start and end of action periods. Variables are exponent including blue or red and scoreComparison of each exponent for each match can be seen in the table provided. It revealed that each silat olahraga exponent performed differ profile of actions indicator. Blue exponent more conquered the matches. Actions used for both exponent (blue and red) are described and explained briefly. The data showed that blue exponent more conquer overall 4 matches as blue opponent have higher tactical skills during matches.The data about the nature of the activity performed within fight periods can be combined with the analysis done by previous study to provide a detailed description of the demands of the sport and assist in the development of specific training programmed. The approach used here would be useful to apply to other sports whose work and rest periods have been investigated to give a greater understanding of the type and frequency of action within the work periods. The comparison of each exponent can be seen in the result.


Introduction
According to Kartomi M.(2011), Pencak silat (‘the art of self defence’) is a contemporary umbrella term used in Indonesia and Malaysia and other parts of Southeast Asia to designate the hundreds of traditional and modern martial art genres that are performed either solo or as a duel, and with or without musical accompaniment.
The requirement and prescription of training programmes for sport requires an understanding of the physiological requirements of the match. Various forms of time motion analyses have been used widely to estimate the nature of specific intermittent high intensity and low intensity activities as they relate to the energy requirements of team sports.
Previous research notated the technique used in defensive and offensive movements such as in mixed-martial arts, boxing and Muay Thai. However, there is no research that specifically describes the activity involved in silat olahraga that specifically describes the activity that contributes to the physiological demands of this combat sport.
The nature of work periods within any combat sports depends on the frequency, volume and type of the activity being performed. The distribution of fight time and break time has been determined in international silat olahraga competition in the previous research, which indicated that 62.6% of the match is spent in fight time (Shapie et al, 2013). The work to rest ratio of 2:1 in silat olahraga might be misinterpreted if people count the action periods performed in silat olahraga in the same way as work periods in field games and racket sports are interpreted.
The nature of “purposeful movement” in team games, rallies in racket sports and action periods in martial arts are very different. Therefore, the objectives of this study are to describe the detail activity that occurs during the fight time of a silat olahraga match, especially the profile of technical event.

Material and Methods
Match analysis
A publicly available video recording of male silat olahraga match from the national silat olahraga competition in 28th SEA Games 2015 held at Singapore was used for the analysis. There are 4 matches used for the analysis; a male quarterfinal match of class A of the 45-50kg, a male semi-final match of class H of the 80-85kg, a male semi-final match of class E of the 65-70kg weight category, and a male final match of class E of the 65-70kg weight category. 14 different types of event performed by the four male contestants as well as the start and end action of periods are identify.
Video sequences were repeated where necessary and the playback rate was reduced to allow accurate measurement of each offensive and defensive movement category. The video could be paused and played back frame-by frame for ease of use. Silat olahraga exponent motion was subjectively categorized by an experienced observational analyst for silat olahraga competition. Information could be entered into the computer system, via representation on the screen of the silat olahraga match, and specially designed screen functions for each exponent (red or blue), action and outcome for each activity. The frequency, mean duration and percentage of total time were subsequently calculated.

Rules
Only Tanding (match) categories require weight classifications. Tunggal (single), Ganda (double) and Regu (team) are open weight events, requiring only age and gender distinctions. Before competing, each contestant must be subjected to two weigh-ins. During each weigh-in, the participants must wear a dry silat costume, without the inclusion of any guards (groin, joint) and sabuk/bengkung (belt/sash).
Each weigh-in has to be done in the presence of a Referee-Jury member or official representatives from both teams. If a contestant is unable to join the first weigh-in and has provided an acceptable reason, his or her name will still be included in the drawing of lots.
He or she will still be permitted to compete, as long as they pass the second weigh-in. The second weigh-in will take place 15 minutes before the start of a match. The procedure and rules for the second weigh-in is identical to that of the first weigh-in; the only difference is that any contestant found to have exceeded his or her category will face disqualification.

Motion categories
Silat olahraga exponent’s motions were coded into 14 different types of categories and were defined as follows:
Punch:
The punch ‘tumbuk’ attack is done by a hand with a closed fist hitting the target. In silat punching is often used to fight the opponent. It can be a straight punch ‘tumbuk lurus’ or uppercut ‘sauk’ to the exponent body’s.
Kick:
The kick ‘tendang / terajang’ is an attacking movement which is performed with one leg or two legs simultaneously. A kick can be aimed at any target. It can be front kick ‘tendang depan’, side-kick ‘depak’ or semi-circular side kick ‘tendang lengkar’.
Block:
The blocking movements begin with the posture position ‘sikap pasang’: the exponent stands straight with his hands around his body or close to his chest. Blocking or parrying ‘tangkisan’ can be done using arms, elbows and legs with the purpose to block off or striking back at any attack.
Catch:
The catch ‘tangkapan’ is done by using the hand to obstruct the opponent from carrying out an attack. The silat olahraga exponent is able to prevent himself from being attacked by pointing the attack which he has caught to another direction. A catch which twists or drags the opponent is forbidden. Also, a catch which could break the part which is being held such as the leg and waist is also forbidden. These regulations exist to protect the silat olahraga exponent’s.
Topple:
There are various ways of toppling down one’s opponent. For example, a silat olahraga exponent ‘pesilat’ can either push, shove the opponent’s back leg from the bag or from the side, shove, hit, kick, strike or punch to make the opponent lose his balance. Every fall is considered valid as long as the silat olahraga exponent topples his opponent down without wrestling or he is able to overpower the opponent whom he has brought down.
Sweep:
Swiping ‘sapuan’ involves attacking an opponent’s leg which are on the ground to unstabilise him and bring down to the ground. A silat exponent can perform this attacking movement either with his right or left leg, Hence, front sweep ‘sapuan depan’ is done by swinging the leg to the front to push an opponent’s front leg, while back sweep ‘sapuan belakang’ is carried out by swinging the leg backward to hit the back leg.
Evade/Dodge:
The evade ‘elakan’ technique is carried out by silat olahraga exponent when he tries to evade an attack. This technique does not require the silat exponent to touch the opponent in fending off the attack. They are many ways of carrying out his defensive movement such as dodging ‘gelek’, retreat ‘mundur’, evasion to the side ‘elak sisi’, bending ‘elak serung’, jumping ‘lonjak’, ducking ‘susup’ and etc.
Self-Release:
Self-release ‘lepas tangkapan’ technique is a technique to unlock any clinch or catch from an opponent.
Block and Punch:
The blocking technique is used to block any hand or leg attack from the opponent and followed by counter attack using the hand to punch the opponent.
Block and Kick:
The blocking technique is used to block any hand or leg attack from the opponent and followed by counter attack using the leg to kick the opponent.
Block and Sweep:
The blocking technique is used to block any hand or leg attack from the opponent and followed by counter attack using sweeping technique to the opponent.
Fake Punch:
An action which a silat olahraga exponent intends to confuse the opponent using a fake punch to break his opponent’s defensive posture.
Fake Kick:
An action which a silat olahraga exponent intends to confuse the opponent using a fake kick to break his opponent’s defensive posture.
Others:
Both silat olahraga exponents are either in posture position ‘sikap pasang’ or coming close to each other using silat step pattern ‘pola langkah’.
All the activities are considered high intensity except for others which at that time both silat olahraga exponents are in low intensity periods.

Reliability of Observation
The author analyzed all the activities and simultaneously classified each change of motion in a 4 separated match. Observations were done separated by 24 hours. It requires experienced silat olahraga practitioners to analyses the data as the movement of both exponents is fast, needing close inspection. The classification of movement was subjective with work being classified according to the instruction given by the referee.

Statistical analysis
The observation generated data will be frequency counted, a method of recording in observational research in which the researcher records each occurrence clearly defined behavior within a certain time frame. All the raw data was inserted into SPSS for more detailed analysis. Statistical analysis was conducted using Statistical Package for Social Scientists, version 21.0 (SPSS, Chicago, IL). A chi square test of independence was used to determine if there was a similar profile of actions performed by the red and blue contestant in the match.

Results
The outcomes are shows in the table below. The action factors used were description of the action, the exponent performing the action and outcome of actions. Each of these reliability results was recorded in Table 1. Table 2 shows the actions performed during the contest and their outcomes in each of the match.

Discussion
Based on the result from the Table 1 and Table 2, group statistics can be found by the SPSS software that being used to calculated all the possible data according to the notated exponent statistics. All the 4 silat olahraga matches are being conquered by Malaysia Team. It shows those Malaysia athletes are dominant to control their opponent during the match’s. The data show in the Table 3 below.

Match 1 shows that Malaysia athlete are doing high error. It can be seen on the Standard Error Mean (SE Mean) in the table. Possibility that Malaysia athlete does little mistakes compared to the Vietnam athlete that makes him can win the match because on this match Malaysia athlete are more tactical skill person. The hit targets are 74.5% for overall matches. Kicks are used the most by both exponents which is 46.4%. Compared to Vietnam athlete, he will keep on attacked when there is a chance without thinking as he keeps on wanted to win the match’s. So that, Malaysia athlete got higher score for each round. Malaysia athletes win based on the statistics recorded along the match’s. As it was the final round, the match’s were a bit intense for both.

Based on Table 3 for Match 2, the SE Mean for Singapore athlete are higher than Malaysia. But still, the match’s are wins by the Malaysia team. 54.1% of kicks actions are used in these match’s. Both exponents are more towards using kicks actions to beat the opponent down. It can be defined that Malaysia athlete got higher skill of knowing the opponent steps to conquer the games without doing higher mistakes compared to the Singapore team. From Table 2 of Match 2, both athletes are tends to used kicks action as the ways to fight with each other. Shows that Singapore athlete kicks more than Malaysia athlete but it could be a fake kick so that it increased the SE Mean for the athlete. During match’s, tactical skills are really needed to ensure each athlete can win the game by the point they could gains using the actions correctly.

Group statistics for Match 3 between Malaysia and Thailand athletes are shown above. From the Table 3 on Match 3, higher errors are being made by the Thailand athletes during match’s compared to the Malaysia athlete. The hit target for both exponent are 82.1% which shows that both have tactical skills that helps them to collect point by hit the target correctly. The kicks action used are 38.9% and punch actions used are 15.79%. Even though the results in Table 1 shows that both athletes are hitting the target correctly, there also occur some mistakes that makes the Malaysia athlete more dominant to wins the match’s. Thailand athlete are so eager during all the 3 rounds for the match, but Malaysia athletes looks a little relaxing to finish all the 3 round. It could be the possible reason Malaysia athlete wins the Match 3. It helps to makes Malaysia athlete doing less error towards match’s and can beats the opponent easily with skills that he has.

Match 4 shows that SE Mean are dominant by Malaysia athlete. Higher error could be seen, but still Malaysia athlete has the tactical skill that helps him win the match's. The match’s are dominant by Malaysia athlete by 70% compared to the Singapore athlete. Both exponent hit target about 75.6% overall the match’s. It is positive variables that show each exponent have their own skill in getting points by points along the matches to win the game. Kicks actions frequently used by them which is 41.6% by the blue exponent which is Malaysia athlete and 58.4% by the red exponent which is Singapore athlete. Malaysia athlete able to topple down the Singapore athlete by 8 times that makes him could get higher score for the match.

Conclusion
Post-event analysis of hand notation indicates that the prototype system developed for this study can be used to record and evaluate a silat olahraga match. This study complemented with those of the broad work and rest study undertaken by Shapie et al(2013). The current study has provided a great understanding of information for the silat olahraga by looking at the activity involved in competition. Both of the exponents performed more high intensity actions than low intensity actions (i.e. the frequency count).
However it is important to understand that high intensity actions will contribute more in the score points (i.e. outcome that count) rather than low intensity actions. There is also a range of frequency in attacking and defensive activities used by both of the exponents. The winner (blue exponent) used more kicks than the loser which may reflect greater skill or fitness or both. However, it is still doubtful that these are the only factors that influence the match.
National silat olahraga athlete needs more tactical skills to be learned as it helps to reduce the mistakes during match. More than that, the national athlete must able to avoid error that might make them less capable to dominant the athlete from other country. The tactical and technical skills must be understood by the athlete to ensure they would have better performance in the next competitions. Indicators listed for the silat olahraga also important as it was the score they could collected for the match.
The data collected would help them to realize their mistakes that they could not know as they were focusing on the game. Coaches and athletes can sit together to talk about the previous match and share their experience towards the game for better improvement and preparations for the other competitions.

Recommendation
It is recommended that future studies determine the full range of activities performed with movement classifications and the variation of strikes that contribute to losing and winning the match.
It is recommended that those developing conditioning elements of training programs for silat olahraga athletes are aware of the frequency and spread of durations of action and rest periods within action periods. The implication from a coaching perspective of the types and frequencies of strikes used would suggest that in training, a large proportion of time needs to be utilized in development of kicking and blocking as well as the conditioning of lower limbs in order to absorbs strikes and resist fatigue during a match to being able to defend and counter attack effectively.
There is a limitation of this case study as the findings here only represent four silat matches from Men class A, Men class E and Men class H, so the findings cannot be generalized to all silat olahraga competition. However, the purpose of this study was to develop a system for monitoring actions during a silat olahraga match (and not establishing normative data).
Furthermore, the system developed is useful in future study in silat olahraga. This was the normal study to provide descriptive detailed information of a silat olahraga match, increasing the knowledge base and providing a methodology that can be used in future research and by coaches. Moreover, the other sports where the frequency and duration of high intensity activity periods fail to provided sufficient information to fully characterize the demands of the sport.
